My friend has twin 70 evinrudes on the back of his sea cat, one of them over heated a couple of days ago, the horn never went off, compression was 120 on all cylinders when I checked them a few months ago, after over heat they are 75, 90, 120...I have removed the head, (pain in the butt, the 4 middle bolts snapped, had to drill and retap) head at machine shop for resurface.
I found a couple of wires that had been very slightly melted, other that that engine looks ok, I ordered new impellers and thermostats/gaskets for both motors, a new head gasket for the one and a new temp sensor. pistons looked ok. any other suggestions on what to check/replace????
